Berberis plant named ‘Hoho 1’

ABSTRACT

A new cultivar of  Berberis , ‘Hoho 1’, that is characterized by its compact plant habit, its moderate growth habit, its young shoots that are deep pink-red in color and its mature foliage that is heavily mottled with pink and red.

Botanical classification: Berberis thungergii.

Cultivar designation: ‘Hoho 1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Berberis thungerii, and will be referred to hereafter by its cultivar name, ‘Hoho 1’. ‘Hoho 1’ is grown for use as a landscape shrub.

The new cultivar was discovered by the Inventors as a chance seedling in a production field in June of 2011 in Zevenaar, The Netherlands. The parent plant is believed to be ‘Rose Glow’ (not patented) as the field contained propagation stock plants of ‘Rose Glow’.

Asexual propagation of the new cultivar was first accomplished by one the Inventors using softwood stem cuttings in Zevenaar, The Netherlands in June of 2011. Asexual propagation by softwood stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar, which in combination distinguish ‘Hoho 1’ as a new and distinct cultivar of Berberis.

-   -   1. ‘Hoho 1’ exhibits a compact plant habit.     -   2. ‘Hoho 1’ exhibits a moderate growth habit.     -   3. ‘Hoho 1’ exhibits young shoots that are deep pink-red in         color.     -   4. ‘Hoho 1’ exhibits mature foliage that is heavily mottled with         pink and red.

The probable parent, ‘Rose Glow’, differs from ‘Hoho 1’ in having a less compact plant habit and faster growth rate, less mottled foliage, and young shoots that are lighter pink-red in color. ‘Hoho 1’ can be most compared to the cultivars ‘Harlequin’ (not patented) and ‘Rosy Rocket’ (U.S. Plant Pat. No. 18,413). Both cultivars are similar to ‘Hoho 1’ in having foliage that is mottled with pink and red. ‘Harlequin’ differs from ‘Hoho 1’ in having a more vigorous growth habit, young shoots that are less deeply colored, and foliage with less intense mottling. ‘Rosy Rocket’ differs from ‘Hoho 1’ in having a columnar plant habit, young shoots that are less deeply colored, and foliage with less intense mottling.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Berberis. The photographs were taken of a plant two-years in age as grown outdoors in a 2-liter container in Zevenaar, The Netherlands.

The photograph in FIG. 1 provides a side view of ‘Hoho 1’.

The photograph in FIG. 2 provides a view of the new shoots of ‘Hoho 1’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘Hoho 1’.

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Berberis.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of two-year-old plants of the new cultivar field grown outdoors in 2-liter containers in Zevenaar, The Netherlands. Plants were grown under average day temperatures of 10° to 23° C. and average night temperatures of 1° to 14° C. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
